For Mac-centric sysadmins in a Windows-flavored world, there are a few essential tools: patience, humility, and RDC. Microsoft's Remote Desktop Connection client is the easiest way for anyone on OS X to manage Windows servers near and far, and the truth is it works pretty well -- not perfectly, but capably. You can trade clipboard contents, print to your Mac-connected printers, and even share your Mac's local hard drives back to the Windows host for speedy file transfers. The last full release of RDC, however, was 1.0.3 back in 2004 -- sans Universal Binary, doesn't play well with Vista, and generally lacks pizazz.
A shiny new version 2 of RDC, rewritten from the ground up as an Intel-native app, has been in beta for months now, and it shows great promise; it's got full compatibility with the latest rev of the RD protocol, and it's downright snappy. One problem though: the beta officially expired today (March 31), and on each launch users are being prompted with the download dialog above (good luck downloading the "Lastest Version"). There isn't a new build yet, according to the Mac BU, and it's safe to keep using this beta; the nagging is annoying but not functionally problematic, and the team is working to quickly deliver a final edition.
Meanwhile, if you're being driven batty by the repeated and futile update dialogs, check out my favorite RDC stand-in: CoRD, the Mac OS X version of the open-source rdp tool. It may not have all the bells and whistles of the official tool (
